Monzo has become the first bank to offers its customers a free credit score service; starting in March the UK digital bank will be rolling the service out over the next few months; customers will be able to see changes in their credit score as well as advice on how to improve or maintain this score; Monzo uses credit bureau data from Experian and TransUnion when making lending decisions but this new service will be powered solely by TransUnion; Barclays has a similar credit score tool that costs their users £5.
